Determines how aggressively the control valve responds when making rate change adjustments. The
higher the value the more aggressive the response is.

• Zero Flow Offset
Represents the maximum duty cycle that is sent to the control valve without producing any hydraulic flow
from the PWM valve. Using too high of a Zero Flow Offset value can cause the product control system to
not properly control low rates.

Hydraulic Seed Controller Settings for Specific Planters

Note: If you are encountering a problem with skips in the field or if the hydraulic drive is not shutting off
properly, you may need to adjust the Zero Flow Offset settings. For more information, see
